Not bad.
What I would recommend is that you don't put any effects as you show the kills. For example, I see that when you did the 360/720 shots, you put a really jittery effect on there (correct me if I'm wrong) and it doesn't go so well. Slowing down the kill near the end is good, like on game winning kills where it slows it down as it gets closer to the kill.
Other than that, nicely done.
